| 摘 要： | 沥青稳定碎石基层在我国沥青路面中的应用越来越广泛,其路用性能的优劣对路面使用寿命影响很大。文章通过浸水马歇尔试验和冻融劈裂试验,对不同级配大粒径沥青稳定碎石混合料的水稳定性进行了对比试验研究。与浸水马歇尔试验相比,冻融劈裂试验更能体现不同级配混合料水稳定性的差异,并能较好地模拟混合料水损坏过程,是评价大粒径沥青稳定碎石混合料水稳定性的优选方法。

| Abstract: | The asphalt treated base is more and more widely used in China,the road service performance of which is vital to the service life of road pavement.Based on the immersion Marshall stability test and freeze-thaw splitting test,the Paper had a contrast test on the water stabilities of large-sized asphalt treated base mixtures with different aggregate gradations.Compared with the immersion Marshall stability test,the freeze-thaw splitting test can better show the differences of water stabilities of the mixtures with different gradations,and can more properly simulate the water-damage process of mixture.The freeze-thaw splitting test is the preferential method for assessing the water stability of asphalt treated base mixture. |
